Abstract
PURPOSE: To stably obtain an accurate rate of a dose of radioactivity for a long term, by mounting a known reference radiation source for forming the reference spectrum to a radiation detector while correcting the attenuation of the energy by grasping a half-life of the reference radiation source.
CONSTITUTION: The radiation energy of a body to be measured and the reference radiation energy of a reference radiation source 11 are supplied to a multiple crest analysis appliance 14 through a proportional pulse amplifier 13 from a radiation detector 10 as composite pulses. The analysis appliance 14 particularly extracts reference radiation energy from radiation energy compounded, and inputs the enrgy to a comparison computing element 15. Meanwhile, the spectra of radiation energy compounded are fed to a radioactivity dose rate computing element 17. In this case, a net γ ray radioactivity dose rate D to be obtained is acquired by the formula as shown in the right side when the reference spectrum of the reference radiation source 11 is N' (I) and the whole spectra compounded are N (I).
